This analysis differs very much from a limited oral story that I have heard. The oral story that I have heard may be very local; it may not be representative.
According to one oral story that I heard, the source of the name ገበሮ are not the Borana but the ገበሮ themselves. They introduced themselves to the Borana who came to their country as ገበሬ and the Borana called them ገበሮ. Given this oral story, what the Professor says about the source of the name is illogical. Why would the Borana use the language of the "other" Ethiopians instead of Borana language to name these "other" Ethiopians?
Intermarriage between the Borana and Gabaro is very much respectful, so classy that a Borana man divorcing a Gabaro woman is considered uncommon. I don't mean to be disrespectful to any side here but that is the oral story I have personally heard years ago, which is very much contrary to the assertion here by this Ethiopian Professor.
While the Borana led the Gada rituals, the Gabaro adhered more to Orthodox Christianity. The latter's leadership in Orthodox Christianity and the differences between names given in the church such as ክፍለማርያም and ገብረማርያም became a source of complaint. This might be a more recent phenomenon. I have been wondering if this difference reflects what happened in Shewa around the time that Orthodox Christianity was introduced circa 1270. I also wonder if the communal relationship between the Gabaro and Borana is qualitatively very different from that between the Borana and Gabra or the Gumuz and Agnuwak, and so on in Ethiopia.
The ገበሮ I know never identified themselves as Amhara. In fact, they identified Amharic speakers as Sidama, as other, not as self.
What kinds of taxes did the Gabaro pay to a Borana, where and when, if the Professor's assertions are accurate?
I have much to learn about this story. But I wish to gain accurate knowledge instead of anecdotal assertions that lack primary source of information from members of the concerned Ethiopian societies who are still alive in millions.
yaballo, do you know what has happened to Dabassa Guyo? A lot can be gained from the traditional knowledge that people like him know.
